A platform for research: civil engineering, architecture and urbanism
AbstractThis report has been prepared by Working Group 13 (WG13) of the International Tunnelling Association (ITA). The question addressed in this report is how the decision is made as to whether to place Urban Mass Transit Systems above ground (either at surface or elevated) or underground. Following collection of a substantial amount of data from 30 cities in 19 countries, representing the situation from 1995 to 1998 (with some later updates), analysis of that data and deliberations on the issues raised has led to the findings and recommendations contained in this report. For many developing countries, the investment cost of a fixed guideway urban mass transit system is significant compared to the national or city economies. In order to assist future decisions, the report recommends that representative decision processes should be better documented and illustrated by reference to current and retrospective studies of typical projects, considering all costs and benefits, real and perceived.
